You can only load a performance tune in one car at a time. You can use it on another vehicle after restoring the stock tune to yours. They are a good investment in my opinion, not only for the performance tuning capabilities but also for speedo correction following gear/tire changes, changing the dcefault traction control setting, raising auto transmission shift points, etc., as well as being usable as a DTC reader. The advertised horsepower numbers realized from the off-the-shelf tunes preloaded in the devices are probably inflated, but some tuners offer custom tuning capabilities to at least maximize the horsepower your vehicle can deliver.
